Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Mattresses can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new bedding should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Best sleep ever!

Undisclosed 9/8/2025

I was really looking forward to receiving this mattress. My old mattress coincidentally was also a Sealy and only a year old and I could notice a difference right away. Ive been having the best sleep since I received it. The only way to improve the mattress would be to add some type of handles. It is a very heavy mattress and moving it is not for the weak.

A firm hybrid mattress that gets more and more comfy

Undisclosed 9/2/2025

So I've been using this mattress for almost a month now and it has grown on me a lot. It starts out pretty firm but was still uncomfortable right out of the gate. It's definitely softened up and is even more comfortable. If you like firm mattresses then this one is for you!

Hybrid Haven for Humans and Furballs

Undisclosed 8/23/2025

From the first night, the DuPont Hybrid II Posturepedic Pro Hybrid, medium mattress felt like sleeping on a cloud that knows exactly where your pressure points are. The PrecisionFit coils and MaxSupport technology truly live up to their promise-my back feels supported, not stiff, and my sleep has been consistently excellent. But the real litmus test? My cat. She has been moving corner to corner claiming this mattress as her personal throne. Whether it's the cool-to-the-touch cover or the gentle bounce of the hybrid design, she's sprawled across it like royalty every afternoon and night. The edge support is solid, which means no awkward roll-offs when she decides to stretch out horizontally. And the motion isolation? Let's just say I can turn over without disturbing her highness. If you're looking for a mattress that blends orthopedic support with plush comfort-and earns the approval of a discerning feline-this one's a winner.

It is the best matress I've ever slept on! 10/10

Undisclosed 8/18/2025

This bed is finally a good bed that doesn't hurt my back. I wake up with no pain, which amazes me.. I bought 2 mattresses before being sent this one for free for my honest review, and every morning, my back and hips killed me. It's firm but not too firm. It's literally perfectly suited to my body. I will keep this mattress for as long as possible. It's a pretty blue color. The setup was so easy. I just had it sat on my queen bed frame. It also inspired me to get a new look for the room and start a cowgirl theme. I absolutely love it! Im so grateful for it. I highly recommend the Sealy dupont 2 hybrid posturpedic matress! Its like sleeping on a cloud literally. 10/10

Best sleep I've had

Undisclosed 7/29/2025

Wow, this mattress is amazing. I got the best night's sleep. This is very comfortable and helped with my hip pain. It's soft but not too soft. It's a little thicker than my old mattress so I will need to buy better sheets. It almost feels like memory foam on the top and with out a sheet the texture of the mattress is like cooling.

She feels like a literal princess!

Undisclosed 7/28/2025

I received this item free for my honest review There is no legit reason why this 17 year old should have a bed this fancy especially since her sister is missing out 😭 but man, is this mattress a dream Even though it is a "Firm" it has a thick layer of memory foam on top that cradles your body and pulls you to sleep. But the spring core really supports someone with back problems ( yes I did take a turn on this, I insist on getting to try it, it was only fair!) The mattress is very responsive I really like it and of course, she loves it!

Sealy Dupont II Posturepedic Pro Hybrid (Firm) - F

Undisclosed 7/28/2025

I've been using the Sealy Dupont II Posturepedic Pro Hybrid (Firm) mattress for a little while now and overall, I'm really pleased with it. I specifically chose the firm option because I prefer more support‚ especially for my lower back‚ and this mattress delivers. It strikes a nice balance between a sturdy, supportive base and just enough cushioning on top so it doesn't feel too stiff or uncomfortable. The hybrid construction is great‚ it feels stable and well-made, and I've noticed a definite improvement in how rested I feel when I wake up. If you're like me and need a firmer mattress to keep your spine aligned, this is definitely worth considering.

Just perfect

Undisclosed 7/28/2025

I am so thankful that we got the offer from Sealy for this fantastic gel memory foam mattress. My husband and me both have back pain and we're looking for something that is firm but not hard and I'm telling you this mattress is just exactly what we are looking for! The first night trying, we both had a very good sleep and woke up with no back pain. We are so happy knowing that it totally works for both of us. The quality feels well-made and luxurious! After a week trying, I don't hear my husband complaint about back pain when waking up anymore. A good night sleep is very important for all of us and this mattress just makes it right!

I've had influenster for YEARS and this is the first time I've gotten a big, let alone a high dollar item. I'm grateful for everything big or small. Now onto the mattress‚ so far I love it! It's comfortable and very nice. One con is it is definitely heavier then my previous mattress but definitely a better structure since it's a hybrid (the last one was all memory foam). I hope it helps me get a better night sleep!

Everything you need

Mishulii 3/14/2025

This is my first experience with Sealy mattress. I am married and have completely opposite needs from a mattress than my husband. Finding a mattress that satisfies both of us is almost a miracle. I need a more firm mattress but soft enough to have my spine leveled and not waking up with a hip pain (I sleep on my side). My husband needs softer mattress because he has lower back pain. I sleep hot so I need the mattress to regulate temperature so I don't get too sweaty but also not too cold. I usually don't like 100% memory foam mattresses because they get too soft (even eventually) and the spring mattresses are usually pretty stiff. This hybrid is perfect medium in my opinion. Thanks to the springs I am hoping it will actually lasts this way. After a month or so we both agreed we have been waking up with no pain and actually rested. I didn't have to cover and uncover a million times throughout the night. So far we are really happy with this mattress and let's hope it will last for a couple years. I think this mattress would be also fantastic into guestrooms since I feel like it would be comfortable for anyone with different needs.

So happy with this mattress!!!!

Caroline 3/10/2025

Sealy kindly gave me this Posturepedic Pro Hybrid Medium, Queen for free so that I could review it. Full disclosure I wasn't expecting to like it this much as I do. We put this in our guest bedroom and have slept on it multiple times because it's so comfy. (we have a king in our main bedroom) IMO it has the perfect amount of firmness-not too soft, not too firm-right in that ideal middle ground. Just be aware that it takes about 2-3 weeks to really settle in, but once it does, it's AMAZING. Really conforms to your body. Pleasantly surprised how much I like the gel memory foam. It provides a nice cooling effect and I tend to sleep hot. Pairing it with a warmer down comforter and quilt is honestly perfection. We are considering getting one for our main bedroom now in King size. Highly recommend!! Good luck on your mattress purchase and hope this helps :)

The best mattress I have ever slept on !!!

Heatherr 3/9/2025

I recently switched my mattress to the Sealy Posturepedic Dupont Hybrid II , it has been the best sleep of my life. The mattress is firm while feeling like your sleeping on air it's as if the mattress forms around your body with alignment to support while you sleep. I often get hot during the night but it seems as if the mattress keeps me cool. My back posture has seemed to improve as well which is wonderful because I don't wake up sore on one side or the other. Overall I highly recommended this mattress my mom has severe back arthritis pain and I have recommended her to purchase this mattress also !!

Best night sleep in years!

Kyle 3/6/2025

Best night sleep I've had in years! I got this bed as a free promotion and I wasn't sure what to expect. I usually wake up several times a night and rotate my body, but since I've started sleeping on this mattress I wake up in the exact same position as when I fell asleep! I can see this mattress becoming a staple in my house in all the bedrooms. I wouldn't be surprised if my guest as where I got these mattresses from when they wake up on one after a solid nights sleep!

Love this mattress

CatMom 2/28/2025

This mattress is extremely comfortable. I came from a mattress that was the old school innerspring that was over 10 years old that I loved. I was hesitant to switch over but I'm glad I did! This mattress was a transition but after a month of sleeping on it, I melt right in but still feel extremely supported. Looking at my sleep tracker, the time I stay asleep and the quality of sleep has gone way up. If you're looking at a new mattress, definitely put this on your list to check out. I will be getting this one for our guest room when it's time

Incredibly comfortable

CLynn 2/23/2025

We are using this as a guest bed but have tested several times ourselves. One of us prefers a firm bed while the other prefers cushioned, and somehow we both love this one. We both have had the best night of sleep on this mattress and are considering replacing our own now. We've had the same feedback from some guests, including one saying they woke up for the first time in years without their normal morning back pain. I absolutely recommend this one!

Best Most Painfree Sleep EVER!!

Kayti 2/22/2025

Im 32 Ive had rheumatoid arthritis since I was 2, as well as fibromyalgia which makes my skin very sensitive and makes non painful stimuli pretty dang painful. This Dupont Hybrid II has made an insane difference in my quality of sleep, my duration of sleep, my comfort and reduced my pain. It is stiff enough to hold my weight as well as allow me to move the way thats needed to find a good position. It use to take me hours to fall asleep, now im out in 15 minutes! My back feels supported my hips are gently hugged and I sleep like a literal baby! I feel so blessed to have had this opportunity and that it has been such a good fit for me! Anyone who wants a sturdy yet soft supportive mattress will love this! Before this mattress my neck was so tight I've been getting vertigo and losing hearing in my right ear, Its now been over 2 weeks since those issues went away. I feel refreshed and my day starts a whole lot better now!

So Comfy and Perfect for Everyone in the Family

Francy 2/21/2025

We have purchased Sealy mattresses before and after trying others (including extremely expensive ones), we went back to Sealy. This hybrid is a perfect compromise for those who prefer semi-firm and those who prefer a plusher feel. We have only been using this specific mattress for a little over a week, but have enjoyed it. Highly suggest this for those in the market for a new mattress.

Luxurious Comfort and Cooling Support!

Cà Chua 2/19/2025

I received the Sealy Posturepedic Elite Hybrid Queen Mattress for free from BzzAgent in exchange for my honest review, and I couldn't be happier with the upgrade! Replacing my old mattress with this one has been a game-changer. This mattress offers a luxurious sleeping experience, featuring a sleek design and premium materials. Compared to my old mattress, the Sealy Posturepedic is incredibly soft and comfortable, yet it still provides excellent support. The cooling technology helps me fall asleep faster and improves overall sleep quality, making nights more restful. I'm so impressed that I plan to purchase one for my kids when it's time to replace their mattresses. I highly recommend this mattress to anyone looking for a luxurious, cooling, and supportive sleep experience!

Best sleep of my life

MayDay164 2/17/2025

I received this mattress for free in exchange for an honest review. I have slept on the mattress for the last two nights, and have truly never slept so well in my life! The memory foam layer on the top is so thick, like nothing I have ever slept on. The there is no movement whatsoever when one person moves, making this wonderful if you have someone that tosses a lot! I feel like I just melted into the bed when I laid down. I would buy this mattress for every bed in my house if I could! I love it!

HopeD 2/16/2025

The quality and comfort are impeccable! I never thought I'd enjoy a firm mattress, but it turns out, this is exactly what I needed for a good night's sleep. It's firm without being hard. After night one, I was already impressed. My husband and I have both never slept better. I used to wake up with back and hip pain and now that's not an issue. We are both comfortable, cool, and supported all through the night. I expect this to hold up for years to come. I recommend this mattress enough! Gifted by Sealy in exchange for my honest opinion.

Very supportive firm hybrid mattress

Angie 2/12/2025

I smiled when I first laid down on my new mattress. I have chronic back and hip pain and this mattress makes my body feel actually aligned and supported. It's a very firm mattress yet so comfortable. And I finally do not sink into the memory foam like my old bed. I am a hybrid mattress convert, it truly is the best of both worlds. I'm having the best sleep of my life since before having kids, and waking up less sore. I received the mattress for free from bzzagent, however this is a dream mattress and am thrilled to own it.

Perfect combination for side / back sleepers!

Lee 2/11/2025

First off, this is a combination of memory foam and coils. I normal stay away from coils but mattresses have come a long way! To make things even better - the top has a COOLING gel layer. Do you know how absolutely awesome that is in Florida? The mattress is quite firm but has a decent amount of give. I recommend it for those who sleep on their backs a lot or side sleepers, which I am. I will buy another for our other bedroom definitely!

The most comfortable mattress I've ever slept on by far!!!

Bk509 2/9/2025

My wife and I both love our new Sealy Posturepedic Pro Hybrid mattress so much! It is by far the most comfortable bed I've ever slept on. My usual aches and pains I would experience upon waking up on my old worn-out spring mattress are gone. I've never slept so well in my entire life! I love the fact that it is a hybrid mattress so it combines the benefits of a spring and a memory foam mattress together. Another plus is that I stay cool throughout the night. I got the queen size with medium firmness and it's perfect for my fellow "side-sleepers". I can't say enough good things about this mattress. The one and only complaint I have is the fact that it is a bit heavy in comparison to a normal spring mattress, but honestly it's probably because it is so well made compared to the average mattress. You can tell that this is a high quality mattress, and the fact that it is made here in the USA makes it that much better. I highly recommend you give it a try and I'm sure you won't be disappointed.

This truly is the perfect balance for a mattress. My sister just stayed with us and commented how she didn't even know where she was when she woke up because she slept so soundly.
